`   R`
`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)
*'(x, *(minus(y), y)) -> *'(y, y)

Furthermore, R contains one SCC.

`   R`
`     ↳DPs`
`       →DP Problem 1`
`         ↳Polynomial Ordering`

Dependency Pairs:

*'(x, *(minus(y), y)) -> *'(y, y)
*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)

Rule:

*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)

The following dependency pair can be strictly oriented:

*'(x, *(minus(y), y)) -> *'(y, y)

Additionally, the following usable rule w.r.t. to the implicit AFS can be oriented:

*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(*'(x1, x2)) =  1 + x1 + x2 POL(*(x1, x2)) =  x1 + x2 POL(minus(x1)) =  1 + x1

resulting in one new DP problem.

`             ↳Instantiation Transformation`

Dependency Pair:

*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)

Rule:

*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)

On this DP problem, an Instantiation SCC transformation can be performed.
As a result of transforming the rule

*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)
one new Dependency Pair is created:

*'(minus(x'''), *(minus(y'), y')) -> *'(minus(*(y', y')), minus(x'''))

The transformation is resulting in no new DP problems.
